sslHealthCheck.response

string

The bytes to match against the beginning of the response data. If left empty (the default value), any response will indicate health. The response data can only be ASCII.

port

is used for health checking. USE_NAMED_PORT: The

object

httpsHealthCheck.port

number

The TCP port number for the health check request. The default value is 443. Valid values are 1 through 65535.

httpsHealthCheck.portName

string
